TRANSFORMATION PICITU RE.

SPECIFICATION forming part of Letters Patent No. 568,778, dated July 14,1896. Application filed March 11, 1896. Serial No. 582,802. (No model.)

' zen of the United States of America, and aresident of the city,county, and State of New York, have invented a new and usefulImprovement in Transformation Pictures, of which the following is aspecification, reference being made to the accompanying drawings.

The object of my invention is to produce a transformation puzzlepicture, so constructed that figures or parts of the. picture may bemadeto appear or vanish at will by a slight movement of a revolvingportion of the picture.

In the accompanying drawings, Figure 1 shows the picture containingeight squares and figures of men. Fig. 2 shows the same picture with thecentral disk slightly turned, so-that the dissected figures again match,but present the appearance of but seven squares and men.

The disk revolves upon the pivotal point "1. and is restricted by thegroove and pin I from making more than a one-eighth turn, so that ateither end of the movement all of the figures will match properly.

In Fig. 1 there are eight squares and eight men. llv'giving the disk aneighth-turn 71 will match with G, y will match F, f pi l match E, (5will match D, (Z will match C, a will match B, and b will match A; butas nothing goes from A to II, the picture will, as shown in Fig. 1,present but seven squares and seven men. Each square and man hasabsorbed a small portion of the missing one, which is so evenlydistributed as to be almost imperceptible and gives the appearance ofone figure having vanished. A reverse movement of the disk will cause aneighth man to evolve from the seven.

The figures, it will be seen, are drawn in sections of a circle,equidistant apart, on the periphery, but at different distances from thecenter of the disk, increasing in regularprogression, according to theline of a volute, as shown.

By the introduction of a second series of figures, drawn upon the lineof a reversed volute, the two principles may be introduced in the onepicture, so that when the figure of one series vanishes the other willappear.

I claim as my invention- A transformation picture divided into two ormore parts, arranged upon movable pieces, each of which contains partsof a sequence of figures or subjects placed at equidistant points, sothat aslight turn of the movable part leads to a new point of contact,n1atch-.

ing the dividing parts and producing variable results, substantially asshown.

Intcstimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 10th day of March, 1896.
